[PATCH v7 0/7] Support for Fujitsu MB86S7X SoCs

[Vincent Yang]

Hello,

  Fujitsu have a series of SoC already shipping based around
variations of 2xCA7+2xCA15 big.LITTLE architecture, and we would like
to upstream the basic support in this series.

  MB86S70 is a big.LITTLE platform with 2xCA7+2xCA15 and an additional
CM3 as the master. MB86S73 is a simple 2xCA7 and an additional CM3
master.

  We will send a pull request for this series in the next few days
if there are no further issues.

Changes since v6:
* s/freqency/frequency in clock driver
* Macros for number of channels and register offset in MHU driver
* Added more comments in Documentation
* Removed unneeded amba_request_regions() from MHU driver

Changes since v5:
* Pass u32* instead of u32 value to/from mailbox api.
* devm_ioremap_resource() instead of devm_ioremap()
* Decrease verbosity of probe success print.

Changes since v4:
* Convert ARM MHU driver to be an AMBA driver

Changes since v3:
* Identify platform, by checking presence of DT node
"fujitsu,mb86s70-scb-1.0" before populating cpu clocks and MCPM
support.
* Disable clock upon gpio module remove
* Lower init level of gpio driver from subsys_initcall to module_init
* Use managed device resource allocation in MHU driver

Changes since v2:
* Minor cleanup of MCPM as suggested by Nicolas Pitre.

Changes since v1:
* Thanks to Arnd, modified clock driver to populate clocks only when
some user need them. Node name changed from "fujitsu,mb86s70-clk" to
"fujitsu,mb86s70-crg11" . Controller+Domain+Port of a clock are now
three cells specified by the user node.
* aliases moved into board DTS files
* Voltage supply moved as per-board DT node.
* Removed default overly verbose loglevel=8
* Specify -march=armv7-a flag for mcpm.c and smc.S that contain ARMv7
specific code.
* Removed wrongly put outer_flush_all(), now using standard
v7_exit_coherency_flush() instead of platform specific macro.
* Simplified GPIO offset calculations in gpio-mb86s70.c driver. And
added .remove() for the driver
* ARM MHU driver provided a .remove() to enable module unloading.
* A few other misc cleanups suggested in v1 submission.

Thanks.
